Compared with MRI or CT, brain biological electrical impedance tomography were performed on patients with supratentorial tumors and healthy people . The AUC (area under the curve) of ROC, which is associated with the increased maximum and the difference between left and right equilibrium of
Background Glioblastoma (GBM) is the most common and devastating malignant brain tumor in adults. Patients with glioblastoma face a poor prognosis. Despite maximal treatment, most patients suffer tumor progression after 6-7 months and die within 1-2 years. Standard treatment for newly diagnosed
Each participant will receive standard monitoring (ECG, SpO2, SBP, BIS, urine output, temperature). More detailed hemodynamic monitoring will be obtained by Edwards Lifesciences ClearSight system (CO, CI, SV, SVI, SVV, SVR, SVRI).
TCI Propofol and Remifentanil will be the agents of choice for
Primary central nervous system lymphomas (PCNSL) are extra-nodal, malignant non-Hodgkin lymphomas of diffuse large B-cell type confined to the CNS or eyes without evidence of systemic spread. PCNSL account for up to 1% of all lymphomas and 3% of primary brain tumors. Despite recent progress in PCNSL
Background
Postural control is an important component of movement. Prior to movement initiation, it is necessary to control posture such as gait initiation. Individuals with stroke often show impairment in both postural control and voluntary movement. The deficiencies restrict individuals with
Brain tumors are the first cause of cancer mortality in children and the 3rd cause in young adults. The most frequent brain tumors are gliomas and among them the most common type is astrocytoma. The most malignant astrocytoma is Glioblastoma (GBM). Standard therapy of newly diagnosed GBM patients
Primary brain tumors in adults are less common than metastatic tumors. The most frequent are glioblastoma multiforme, metastases, anaplastic astrocytoma, meningioma, pituitary tumors and vestibular schwannoma. 70% of the tumors in adults are supratentorial. The most infratentorial tumors are

Normal saline or 0.9% sodium chloride solution is the most commonly used intravenous fluid worldwide and its composition are 154 mmol Na+ and 154 mmol Cl- per litter with osmolality of 308 mOsmol/L. That composition is not "normal" because plasma contains potassium in range between 137-146 mmol/L,
Available clinical evidence on the use of dexmedetomidine sedation in neurosurgical and neurocritical care is limited and no definite conclusion can be drawn. There is a need for The use of dexmedetomidine might be a useful adjunct in clinical situations when the increase in CBF could be detrimental
A randomized, double blind, controlled trial will be conducted in neurosurgery ward, operating room (OR) and intensive care unit (ICU) in Tehran, Iran. After a full review of the inclusion and exclusion criteria and explanation of the risks and benefits of the study, written consent form will be
Primary Objective To determine the safety and feasibility of reducing the time interval between LITT and the start of chemoradiation to ≤ 7 days.
The primary endpoint (binary) for safety/feasibility will be defined as the occurrence of one or more of the following within each patient during a window
Fluid therapy is aimed to compensate for fasting which is required for surgery, to meet the ongoing fluid losses and to maintain electrolyte balance during surgery. Fluid deficit of a healthy child who is not fed parenterally may be estimated by multiplying hourly maintenance requirement for fluid
BACKGROUND Radiation Necrosis: Stereotactic radiosurgery has become integral in treatment of brain tumors and arteriovenous malformations (AVM). In up to 10% of cases, this can lead to radiation necrosis (RN) with significant surrounding vasogenic edema and mass effect. Medical treatment for RN
